DUVIPING-*CAFL SPECIFICATION forming part of Letters Patent No. 634,874,dated October 1'7, 1899.

Application filed June 7,1899. Serial No. 719,678. (No model.)

. T LIZ whom, 'it may concern:

Beit known that I, ROBERT E. BROYLES, a citizen of the United States,residing at Chattanooga, in the county of Hamilton and State ofTennessee, have invented certain newand useful Improvements inDumping-Cars, of which the following is a specification.

My invention relates to that class of dumping-cars which are providedwith hopper- 1o shaped bottoms or pockets for holding coal, ore, and thelike and which are also provided with doors which may be opened todeliver the contents of the car and may be closed and locked when it isdesired to till the car with i 5 material to be transported.l-Ieretofore complicated mechanism has been employed for opening andclosing` the doors.

The object of my invention is to provide simpler mechanism for thispurpose.

I may construct the body of the carin any well-known way, and I provideeach door with a sliding bolt which is operated in an improved way by ahand-lever, and each door is provided with a foot-lever by which it maybe closed.

In the accompanying drawings, Figure lis a bottom plan view of adumping-car embodying my improvements. Fig. 2 shows a transverse sectionon the line 2 2 of Fig. l. Fig.

3o 3 is a perspective view showing details of my improved devices foropening and closing the doors. Figs. 2 and 3 are on a larger scale thanFig. l.

The body A of the car may be of any usual construction and may bemounted in any approved way. The car shown is provided with a series ofhoppers or pockets B. These may be of any desired shape, width, andlength, and each one of the pockets is provided with 4c a hinged door C,which opens and closes the bottom thereof. Each door is hinged at one ofits edges c. When closed, t-he door is preferably arranged to enter arecess c/ in the bottom or mouth of the hopper, so as to lit snuglytherein, as indicated at the left-hand side of Fig. 2.

Each door is provided with a sliding bolt D. This bolt is arranged toslide in the guidestraps E, secured to the bottom of the door,

5o and also to slide into and out. of a lockingstrap F, secured to theframe of the hopper.

By sliding the bolt properly the door may be locked or unlocked in themanner illustrated in Fig. 2. The outer end of each bolt-that is, theend next to the side of the car-is connected by means of a link d with ahand-lever G, which is pivoted at its inner end g to a bracket H,secured to the frame surrounding the mouth of the hopper. The linkdisjointed to the hand-lever G between the point g and the outer orhandle end of the lever. Each door may be provided with one or morebolts of this character. One is snflicient when the doors arecomparativelysmall, butwhere very long doors are used an additionalnumber of bolts and operating mechanisms may be employed.

lach door is provided with a foot-lever I, which is secured to the doornear its inner end-that is, the end opposite the hingeand it is ofsufficient length to afford the requisite leverage and also to projectto the side of the car when the door is opened, as illustrated at theright-hand side of Fig. 2. Then the door is opened, the attendant may byputting his foot on the outer end c' of the lever cause the door to bemoved inward and upward, and when the door has been moved fully inwardthe llever G may then be operated to shoot the bolt. The foot-lever isnot only secured to the inner end of the door, as before stated, but itis also connected therewith by means of a branching brace Aif', which isconnected to the lever I, preferably at about one-third the distancefrom the inner end of the lever to the outer end thereof, and thisbracing-arm is also connected at to the door between its central portionand its outer or hinged edge. By this means the lever is madesufficiently rigid so that when pressure is placed upon the lever thebracing-arm t Will take part of rthe strain and prevent the lever frombeing bent. This mechanism has been successfully used. It is muchsimpler than the complicated mechanisms before employed and operateswith entire satisfaction.

-I claim as my inventionl. A dumping-car provided with a hinged door, asliding bolt carried by the door, a

hand-lc ver pivoted to the car-body, and movable about a pivot parallelwith the axis of the hinge of the door, and a link jointed to IOC thebolt and jointed to the hand-lever between its pivot and its outer end.

2. The combination of a car-body provided with a hopper, a door hingedat the mouth of the hopper, a sliding bolt, guide-straps on the door inwhich the bolt moves, a locking strap into which the bolt moves, ahand-lever hinged to the car-body and movable about a pivot parallelwith the axis of the hinge of the door, a link jointed to the end of thebolt next to lthe hinge and jointed to the operating-lever between itshinge and its outer end.

3. The combination of a oar-body provided with a hopper or pocket, adoor hinged thereto, a bolt for looking the door, a lever for moving thebolt, and a foot-lever attached to the door near its inner end andprojecting at right angles therefrom to an extent suflicient to enablethe attendant to close the door by his foot.

et. The combination of a ear-body provided with a hopper or pocket,having a hinged door, a sliding 'bolt carried by the door, straps on thedoor in which the bolt moves, a lock- ROBT. E. BROYLES.
